Nitrate Loading Calculations (continued) <br />Notes: <br />1. Ave Monthly precip, for Lodi, Western Regional Climate Center <br />2. Estimated Average monthly runoff volume; zero assumed for this site with full on-site retention of rainfall level site. <br />3. "Available precip" equal to ave.monthly runoff volume precip minus estimed runoff volume. <br />4. Referenced Eto obtained from CIMIS Zone 12, Eastside Sacramento -San Joaquin Valley; Represents Value for lawns and other uniform turf areas. <br />S. Actual ET adjustment based on the site specific landscape/plant cover (fractional multiplier); see below for calculating "composite factor", 0.55 for this site. <br />6. Net rainfall recharge (" deep percolation") equal to Availbale precip (3) minus Actual ET (5); Negative values set to zero. <br />Calculation of Composite of Ef0 Adjustment Factor for Hypothetical Residential Lot <br />a.
